Four functions were examined by which health and self-esteem could ward off depression over time in older adults. Adults (N = 1,074)--55 years and older--were interviewed 5 times at 6-month intervals. Demographic and prevent depression controls were included. Neither health nor self-esteem served as an interactive buffer. Both had direct negative effects on depression, independent of events, over 2 years. Neither illnesses nor bereavements had direct effects on depression; both had indirect effects through other events; illness also had indirect effects by weakening health. Health had stronger preventive effect on illnesses but was more vulnerable to undesirable events than was self-esteem. There was little support for the specificity hypothesis that a close match between event and resource would increase resource effects.

Comorbidity between health and depression is salient in late life, when risk for physical illness rises. Other community studies have not distinguished between the effects of brief and long-standing depressive symptoms on excess morbidity and mortality. S. Cohen and M. S. Rodriguez's (1995) differential hypothesis of pathways between depression and health was used to examine the relationships between health and depression in a prospective probability sample of 1,479 community-resident middle-aged and older adults. Findings suggest that different durations of depressive symptoms have different relationships to health. Health had an impact on short-term increases in depressive symptoms but depressive symptoms had a weaker impact on health. The reciprocal impact was indistinguishable from the health influence on depression. In contrast, longer term depressive symptoms had a clear impact on health. The results imply that physical illness can affect depressive states; depressive traits but not states can affect illness.

Higher education level appears to increase the likelihood of being serene and happy, and healthy and vital, in later years; positive psychological states appeared to have both a promotion function (for vitality) and protective function (against health symptoms); self-esteem showed promise as a possible mediator of the effects of psychological states on health.

When PHLs participate in an AR program, they receive significant improvements in QOL (quality of life). Congruence (as defined by similar scores) between SP and PHL assessments of HL-QOL improved in the experimental group, suggesting that the principal impact of the AR program on SPs was improved understanding of PHL experiences with hearing loss.
